You could grow chives from seed in a pot, but you can also dry chives to use in soups during the winter. Chives dry relatively easily. I chop mine up in 1/8" - 1/4" pieces, spread them out on a cookie sheet and leave them in my (gas) oven. The pilot light keeps the oven warm and dry so you don't have to even turn it on. I usually leave my chives in the oven for a day or two, until they are brittle. Then I store them in an airtight container.
I use dried chives for soups and savory spice mixes.
Do you grow chives? What do you use them for?
